Our current selection of Botany and Ecology classes and workshops for adults for this season at Coastal Maine Botanical Gardens.


Field Identification of Mosses and Liverworts

with Ralph Pope
Wednesday-Friday, June 21-23
10 a.m. – 4 p.m.

Learn to identify mosses (including Sphagnum mosses) and liverworts. Sessions will focus on field and laboratory identification using the various habitats of the Coastal Maine Botanical Gardens as our field site. This course is intended for beginners and intermediates. Some experience with vascular plant identification and the use of keys will be helpful, but is not required. Please bring a hand lens if you have one.

This class is an elective of our Certificate in Native Plants and Ecological Horticulture program, but it is open to everyone.


Identifying Difficult Sedges

with Lisa Standley
Saturday and Sunday, July 22 and 23
10 a.m. – 4 p.m.

Carex subgenus Vignea contains the most difficult groups and hard-to-identify species in the genus. In this advanced two-day course, we’ll learn to recognize the major groups and common species, and how to use the keys and other identification tools. Day 1 will be an indoor lecture and laboratory session, and Day 2 will be in the field. Please bring a good field guide (Flora Novae Angliae, The Sedges of Maine, Field Guide to Carex of New England), a millimeter ruler, fine-pointed forceps, and a hand lens with 12X or higher magnification.


Butterflies, Caterpillars and the Plants That Feed Them

with Andy Brand
Friday, August 11
9:30 a.m. – 12:30 p.m.

There are over 110 species of butterflies that call Maine home. Butterflies not only add color and grace to our gardens, they are also valuable pollinators of many plant species. Join Andy and learn which plants will attract butterflies to your yards along with the host plants on which eggs are laid and caterpillars eat. All things butterflies will be discussed from their remarkable lifecycle as well as how to identify some of the commonly encountered species. Following a slide presentation Andy will lead participants on a leisurely walk through the Garden and highlight plants valuable to butterflies and identify any species flying about.

This class is an elective of our Certificate in Native Plants and Ecological Horticulture program, but it is open to everyone.


Birds and Botany of Hog Island

with Bill Cullina, Melissa Cullina, and Steve Kress
Thursday – Sunday, August 24-27
Prices include all meals, lodging and transportation to Hog Island

Join National Audubon’s Steve Kress and CMBG's Melissa and Bill Cullina for a special workshop featuring the botany and birds of Audubon’s magnificent Hog Island. The cool headwaters of Muscongus Bay and more than 100 years of protection have favored the growth of one of Maine’s most pristine spruce-fir forests. On this 300 acre sanctuary, you will find a dense moss ground cover and towering conifers interspersed by sphagnum bogs, meadows of hay-scented ferns and a rocky shoreline interspersed by sand beaches. The program includes practical methods for improving backyard gardens for birds using native plants, forest ecology and botany walks through the Hog Island forest, and a seabird cruise to Eastern Egg Rock. This class counts towards elective credits for our Certificate in Native Plants and Ecological Horticulture program, but it is open to everyone..


Flora of Indiantown Island

with Melissa Cullina
Wednesday, September 6
10 a.m. – 1 p.m.
Co-sponsored with Boothbay Region Land Trust

Explore and “botanize” along the trails and shorelines of Indiantown Island on this excursion with CMBG botanist Melissa Cullina. Melissa will teach you about the plants adapted to life on the island, and will describe how understanding the island’s flora contributes to CMBG’s new collaborative project to document the flora of the Mid-coast region. Please bring a life jacket, hat, and hand lens (if you have one – we will have extras) and pack a lunch. Meet at the Knickerkane Island boat launch on Barter’s Island Road. Boat transportation to island provided by BRLT. Please contact the Boothbay Region Land Trust to register.
